摘　　要：文中提出了瞬间情景意识的概念,利用快速呈现的场景图片模拟驾驶员注视点回到道路后看到的驾驶场景,研究了自动驾驶过程中驾驶员的瞬间情景意识的影响因素及感知特性.实验要求三组不同驾驶状态下驾驶员,在听到接管提示后感知情景,判断情景的危险等级并回答与情景相关的问题.结果表明,(1)驾驶员分心会降低情景的感知正确率,且驾驶时玩游戏比与副驾驶聊天分心程度更高;(2)情景的呈现时间越长时,驾驶员对情景的感知正确率越高;(3)情景的呈现时间越短,驾驶员对危险识别的正确率、危险等级判断的正确率越高.The concept of instantaneous situation awareness was defined in this paper.The scene images with fast rendering were used to simulate the real driving scenes when the attention of drivers returned to the road.The influence factors and perception features on drivers＇ instant situational awareness were studied in the automated driving.The drivers were divided into three groups in the test and were required to judge the hazard rating and answer the related scene questions after hearing the alarm.The results show that：（1） The distraction will reduce the accuracy of drivers＇ scene perception,and the degree of distraction in playing games during driving is much higher than the behavior of chatting with the copilot;（2） The longer the scene presents,the higher accuracy of drivers＇ scene perception will be;（3） The shorter scene shows,the higher accuracy of hazard perception and hazard rating will be.
